Abstract (en)

[origin: EP3252754A1] A display device and a gate driver circuit (104) of the display device are disclosed. The display device includes a shift register that shifts a gate pulse (Vgout) in accordance with a shift clock timing and sequentially supplies the gate pulse (Vgout) to gate lines (G1, ..., Gn). At least some of stages (S1, ..., S1085) included in the shift register includes a discharge blocking node (DB) connected between a low potential voltage terminal supplied with a low potential voltage (VSS1) and a second transistor (T2a, T2b), and a discharge blocking circuit (DBC) configured to charge the discharge blocking node (DB) when a Q node (Q) is charged, and discharge the discharge blocking node (DB) when the Q node (Q) is discharged.
